[Mne_analysis] Classification result by dropping some side electrodes

hi,

how many trials/samples do you have? What is the variance of the accuracy
over folds? I am asking to know if your conclusions of "better" are strong
or could be due to variance/randomness in the estimation.

Surprisingly I got better results by choosing the electrodes on the sides than the case when choosing the electrodes over the motor cortex?
